To all 'inkom iat-may oonceml' Be i .known-'that I, FRDERicx'H'nA'rH, a

citizen of theUnited'States, andaresideritv of Tacoma, inv the county of Pierce and '.5 State of`.-Washington, have invented anlm proveinent in Hollow-Wall Construction, of

. whlch :the following is a specification.

I construct-`aireproof wall by means of a hollow block or tile having web members loads"are carrled directly u on aline or practically continuous vertica members, the

locks or tiles-being laid on their sides or `horizontally instead of vertically, asis the is custom, so that the webs are over Webs and v-5 voi ls vare over voids.

f`,-'I1-carrying out my invention .the chief feature is the manner of laying blocks having. a series of .voids arranged longitudi` nal-ly, theblocks being laidin such relation .to'each other in adjolning courses that the vtfebs of eachblock in one course are in direct vertical alinement `vwith the webs in the next one, and the central void of each block is in tween the blocks in the. adjacent courses.

"Inthe accompanyingdrawing,

Figure 1 is a sectional perspective of a 12 Ahollow wall, each course composed of .30 one half' or single block 'or tile and one `double block-or tile arranged and beddedccording. to my invention. Fig. 2 Vis a similar view of a 16 wall, ceri tain courses-being formed of two double' vfblocks and the intervening or alternating courses'being formed of onedouble and two hilf-nais..

In Fig. 2,. one course or horizontal layer is `formed of two" wholel blocks' a and the next one isformed of a whole block a and two half blocks Z2, the latter being on the outside and inside and the whole. block intervening.

The several blocks are bedded inin'ortar but the vertical spaces between them a're left free or open, thus forming a series of nai'- roW dry-air chambers. The blocksfbeing laid sidewise or latwise, they are. well bedded and the blocks directly between the webs are properly lled with mortar.

-A vwall of any desired thickness may be laid with the blocks -and the webs and outer of each block is 'in vertical alinement with 90 the' space between adjacent blocksin the next course above and below, as clearly shown in Figs. l and which is a feature of primev importance .in hollow? wall con` 95 The thickness of the webs will ofcourse be increased for'heavy wall loads.
